Circuit Connection Positioning Of High Voltage Disconnect Switch
Date: | Read: 6
The mechanical structure of device High Voltage Disconnect Switch allows for opening and closing operations even when no current is flowing. Its contact device achieves contact and disconnection through a mechanical transmission mechanism, creating a clear air insulation gap, thereby completely isolating the voltage source of a section of the circuit from downstream equipment. Since this device lacks an arc extinguishing mechanism, operation necessarily requires first terminating the current carrying capacity with the help of a matching circuit breaker before implementing the isolating switch action to ensure that the isolated node is truly in a "zero energy" state.
